"In the past, people made a communication through meeting each other or using memoes and letters. only for few kilometers distance, they had to go for correspondence or had to wait for someone like post officer who can deliver their letters. But over the past century, lots of changes have taken place in the commuication field. In 1930s, telephone come to various places over the world which let to the immediate vocal communication through lines.
Today most of us use a telephone as a fast and easy tool. But this is limited to vocal communication. i.e. we need to say words for communication with a phone. We, however, can find information in other forms. For instance, it requires us to read a written data, if we want to find a book or a speech of a presdent in a library. This kind of information is hard to get with a telephone.
It is also hard to get pictures with a phone. We can use a fax machine using telephone line for trasferation of written informations or drawings. This way, however, is slow and costs high. Over the past two or three decades, we can forward written or drawn informations to far distance in a cheap and fast way, due to a technical development. We call this development as a personal computer."
